at the numbers as we're about to here in a minute, if governor romney doesn't win ohio, it becomes very hard for him. so, ohio, wisconsin, iowa, probably the big fire wall for the president. >> and for romney, what does he have to do? >> he's got to win ohio. we'll go through it here, but ohio is just a key state for him because if he doesn't, then he has to pick up a lot of other states on the map. let's take a look now, actually, at the route for governor romney. if he gets ohio, we'll give him ohio here. we'll also give him florida and north carolina's two states where he's doing well. then we'll also give him virginia, with its 13 electoral votes. we're starting here with a map of other states that he would definitely get. well, now you've got him to 266. now he can take any one of those remaining five battleground states to win. even little four electoral votes from new hampshire. so, that shows you why ohio is such a big deal. if we take ohio off of the map now, that takes him down to 252. >> well, my question s of those that you just showed, how many of those states is he leading in?
